Answer: C) neither.
Explanation: A simile is a figure of speech that consists in making a comparison between elements that aren't obviously related, this comparison is made using the words "like" and "as." A metaphor is also a comparison but it is direct (it doesn't use the words "like" or "as"). The given sentence isn't an example of a simile, nor a metaphor, because it isn't comparing elements, when it says "velvet shoes" it is just describing the shoes using an adjective.
